Bitchy spam

Since when did spam become so bitchy? Take this “comment” for instance:

The next time I read a weblog, I hope that it doesnt[sic] disappoint me as much as this. I mean, I know it was my option to read, but I basically thought youd[sic] have some thing intriguing to say. All I hear is actually a bunch of whining about some thing[sic] that you simply could fix for those who werent[sic] too busy looking for attention.

Followed by a link trying to sell you some crappy imitation shoes, or whatever.

On all my blogs I moderate the comments that make it through the spam filters, but even if it were a genuine comment, who would leave a bitchy comment like this up on a blog?
